Rigid collision, incredible work with the pcb. Can you post the full code that you are using?

Thank you,

Lucian

Hi luciansima80

Does that mean not using a stepper motor and changing the drive to a servo or an electric motor with a gear train?

No, i meant to add the servo motor brake or a gear system.

I addded the servo brake because it was easier, when it stops it has a very slight jitter and can move away from the desired position with approx. 1 mm. For N scale this is a huge problem so i added the servo to keep it in place as it stops.

Hi all

Can anybody assist me please, I've had a change of layout design and now only have 2 roads to and from the TT. I'd like if possible for it to turn anti-clockwise each time, from the 6 'o' clock position (the head being at 12) so the head rotates back round to the 7 and then slightly on again to the 6 'o' clock when instructed to.

Do I leave out the first set of instructions in the sketch regarding myStepper2 'forward' and the first set in the 'position' instructions ( the 'moveTo' )

Like Lucian, mine also sits and makes a high pitched noise when at rest

Any help would be greatly appreciated.

Thank you

Hello, i used the code posted by luce001 on page 7. You should use the servo brake or a gear transmission.

 

Hi Lucian

 

I used one of these from eBay

Hi, thank you. It seems to be almost same to what i used.

In the meantime i found the problem. I build the turntable incorrectly, the deck was touching the well making it very hard to move in some places.

I also installed the servo and now i am very happy with it.

I will also try the screen and buttons.

This is a very helpfull topic and i thank you all for such a great tutorial.

Hello,

Please help me with a small issue.

I've put the motor on my PECO N scale turntable and the precision is a little bit bad. If i reset the arduino and i turn the table in a position i have marked previously, there is a difference the size of a rail width.

I have increased the speed and acceleration in the code and i will reduce them to see how it is acting.

I also want to ask you about the hall sensor, how it should he positioned? In line with the magnet? Higher or lower? Farther or closer?

It is also not the same one as in this tutorial, it is this one

Do you think it is ok or do i need a different one?

Thank you,

Hello,

I build it and I am at the stage where I test with address 200.

Everything seems to be going great, however I have a question. When the motor stands still it emits a continuous beeeeeep. Is there a way to make it quiet?

And another question to be sure I got the wiring of the motor correct. When it initializes should it move clockwise or counter clockwise?

Thank you,

Lucian

LE: I used the latest code and the noise is gone. It's great. Still I am curious about my other question, currently it is turning counterclockwise. Thank you.

Here is the video

sorry for the bad quality

Hello friends,

This is a very inspiring topic and I am going to try it with an N scale peco turntable.

The bits are on the way.

I have 0 programing and electrical knowledge so if I will do it then anyone will be able to do it.

I will keep you updated and if I ask some "basic" questions I apologize in advance.

Thank you,

Lucian

LE: I forgot to mention the bits cost me not more than 50 EUR from Aliexpress (including cables, pcb and breadboard, power supply). I didn't include the rubber mountings and turntable.

If anyone wishes to start this project and doesn't mind the long waiting time, it might be worth it to look on Aliexpress.

I downloaded the libraries and the code compiles ok. For now I just stare at it
